It looks like a chimney… but it’s not! At a fossil fuel burning power station the chimney looks like this:

So what are these enormous concrete monstrosities? These belching behemoths are cooling towers. In the UK’s creaking, outdated power stations coal is burnt to heat water to steam. The steam is sent through turbines at high speed generating electricity. Once through the turbine a huge amount of energy remains in the hot water. For some reason the geniuses who designed these power plants decided that instead of using this heat for something useful like… er… heating… they would call it ‘waste heat’ and fart it into the sky. Some power stations also fart the heat into rivers killing fish. Great move guys!

The really stupid thing is that this electricity is then transmitted along wires to houses where, yes, you’re not going to believe this; it is used to generate heat in electrical heating devices. This process is massively inefficient. More than 75% of the carbon in those lumps of coal is released into the atmosphere for no good reason at all.

This insanity goes someway to explain why countries like Denmark and Sweden are so much more efficient then the UK. When I was in Copenhagen for COP 15 it was exciting to see a small power station within the city limits. This power station only had a chimney. It didn’t need cooling towers because all the ‘waste’ heat was being piped into the city to keep the homes snug. There are no boilers in homes over there (so no need for a boiler scrappage scheme); just large tanks storing the plentiful hot water. Using the hot water produced from generating electricity to heat neighbourhoods is known as district heating or combined heat and power (CHP). Most exciting of all was the giant company name emblazoned on the side of the building… DONG energy. This is clearly the way to warm a city!

It is almost certainly not a coincidence that the countries that lead the world in energy efficiency are also the countries with the highest levels of equality. Efficiency and equality are two noble steeds drawing civilization forth to a better future.

The flip side to the gross inefficiency that lies at the heart of our green and pleasant land is that enormous efficiency savings and therefore emission reductions are readily available. All the government has to do is legislate to pass an Emissions Performance Standard (EPS) to ensure our electricity supply is subject to similar efficiency rules as everything else in our lives (fridges, cars, homes). Simple, you might think. Well it is, but unfortunately, politicians tend to be the snivelling dishonest type. In their quest to service the needs of big business they fail again to serve their true constituency… the people.

The big 6 energy companies in the UK have a great time enjoying both a deregulated market and historic and ongoing megasubsidies (£1676 million a year since 1990). You would think all this money might be spent on innovation, new technologies or improving service. Unfortunately as with the deregulated rail network we get increasing prices and worse service. Deregulation was supposed to give the consumer more choice but the myth of the free market flounders yet again. The ‘Big Six’ meet regularly behind closed doors racking up profits by keeping domestic bills broadly ‘in line’ with one another, restricting energy supplies to competitors and demanding laborious accreditation and credit requirements for new companies. As MP Alan Simpson points out deregulation has delivered an energy cartel but not energy security.

Instead of moving us to a new energy model the government is putting its’ efforts into an approach The Big Six approve of. It’s called Carbon Capture and Storage (CCS). This involves capturing pollution at the chimney and pumping it underground. Despite the fact that this makes power stations 20% less efficient and despite the fact that its effectiveness is yet to be proved the government is throwing a £9.5 billion subsidy at it in the building of four new coal-fired power stations. Describing this as throwing good money after bad is the understatement of the millennium. This ‘solution’ is the same old bullshit with a new hat on. It’s still big, it’s still dirty it’s still inefficient… and guess what?… you’re still paying for it! Families will have to pay a new levy on electricity bills for at least the next 20 years in order to fund this dubious technology that keeps us bound to burning fossil fuels for years to come. The government continues to rein back the noble steeds backing instead the old inefficient knacker ridden by the big fat cats.

Instead of tackling the pollution at its source the government is focusing its energy down stream on the consumer despite the fact that by this point most of the enegy has been wasted already. In this Act on CO2 advert the government skilfully uses fear and the love of our children to try to create behaviour change.

However, there isn’t much point telling people to unplug their mobile phone chargers when the companies doing the charging have a carte blanche to tip us into apocalyptic meltdown and the electricity being delivered to your house is dirtier than an oil spill in the Persian Gulf. Yes, the future is scary, in large part because our leaders are cowardly and are not making the bold joined up move to a low carbon future we so desperately need.

The government should commit to building no more old-school power stations. Instead of enormous power stations in the countryside let’s see smaller power stations around cities burning waste, secondary bio fuels and other fuels and making use of all the heat generated by connecting up to district heating networks. All new homes built should be on brown field sites joined to such a grid.

If the government doesn’t join up it’s messaging to electricity users with that to generators it risks losing any credibility on climate change when we need leadership from government most. Right now this would be a disaster and would undermine a lot of the good work that Act on CO2 has done on the consumer side. We need to prioritize our actions in such a way that those that reap the greatest reductions in emissions are enacted first. Of course, the biggest polluters must be looked at first and hardest. By wimping out of regulating Europe’s biggest polluters what message is the government sending to us?

The usual suspects?

The repeated failure of our government to take appropriate action and reign in the power companies gives concerned citizens only one course of action. As Al Gore, Sir David King and a UK jury have made clear civil disobedience is now urgently required. Is it is time to break the law for a higher cause?

Are you optimistic or pessimistic about the underlying nature of humankind? How much hope do you invest in our future? Depending on your perspective global warming will seem like either a crisis or an opportunity.

If you are pessimistic about the nature of humans then you probably believe that we are competitive creatures whose purpose in life is to consume resources acquire land and wealth and ensure we get laid to pass on our selfish genes. For people with this mindset the solution to global warming is depressing. In order to survive we must create a global treaty to limit the emissions of fossil fuels which in a fossil fuel powered economy means limiting consumption, travel and almost everything else. I.e. the solution is a cost that must be borne.
An alternative perspective is that the current crisis is actually a period of punctuated evolution. Humanity is undergoing a rapid transition to a higher emergent evolutionary stage.

The follow up to the Kyoto Protocol is a treaty designed by humans to determine the composition of the atmosphere. That we could even influence such a thing would have seemed impossible even 1 generation ago. However, it is true, and the composition of the atmosphere will determine more then just what we are breathing; it will also determine the surface temperature of the entire planet, which has ramifications for every ecosystem on earth.

Humanity has been transformed within a few thousand generations from a gawky primate emerging blinking from the forests out onto the Savannah into a planetary force. Not since the first bacterial cells appeared in the primeval soup has one species been so responsible for the future of life.

As our activities change the planet’s chemistry our electronic neural network is increasing in density. Humanity’s collective mind is going global. Soon there will be more neural connections in the global brain then there are in an individual’s brain. A tipping point is being approached.

It’s too late to go back to the trees. We have already changed the planet so drastically that only we can restore ecological balance by creating the structures necessary to regulate ourselves. This requires an ethical and philosophical leap of the same magnitude as the technical leap which has turned us from mammoth clubbers to planetary engineers.

The solution to global warming requires that we shift from competitive economies in which well being has been declining whilst wealth increases to cooperative economies in which creativity and wellbeing are paramount. We must consume less, share more, protect the natural world and work together as a unified species with a shared set of goals for the first time in human history. The needs of nations must give way to the needs of Gaia… planetary cooperation… sounds pretty damn good to me.
